The email API service checks the request and makes sure everything is correct. It also verifies that the sender is allowed to send the email.

How to Integrate an API Email Service with Your Application
Integrating an API email service with your application is easy. You don’t need to write a lot of code. Just follow these simple steps:
Step 1: Choose an Email Service API Provider
First, you need to pick a good email API service provider. There are many options, so compare them and choose one that fits your needs. Some providers offer free plans, while others charge based on how many emails you send. Look for one that is easy to use and has good customer support.
Step 2: Get API Keys
After choosing a provider, sign up on their website. Once you create an account, they will give you API keys. These keys are like a password that allows your application to send emails through their service. Keep your API keys safe and never share them with others.
Step 3: Install SDK or Libraries
Most email API providers offer SDKs (Software Development Kits) or libraries for different programming languages like Python, Java, or PHP. These tools make it easier to use the API without writing too much code. Follow the provider’s guide to install and set up the SDK in your application.
Step 4: Send a Test Email
Before using the email service for real users, you should test it. Write a small script using the API and send a test email to yourself. If you receive the email, the setup is working fine. If not, check for mistakes and fix them.
Step 5: Monitor and Optimize
Once your email API is working, you should track how well it performs. Many providers offer analytics, which shows how many emails are sent, delivered, and opened. If emails are not reaching users, check for problems and improve your setup.
